Mount chandeliers This hook must always be isolated from the chandelier (lamp) with Mount chandeliers PVC tube.This is necessary to prevent potential in the metal reinforcement of concrete slabs or steel pipes in violation of the insulation in the chandelier (lamp).If the wooden ceiling, preferably screwed into a hook, the design of which provides for the presence of the thread (Fig. 1a).And if there is no hole in the concrete ceiling, it breaks down and passes the stud (Fig. 1d), which strap is fixed on the other side beams.In the case of the stud can be provided and the setting plug (Fig. 1, d).

To attach fixtures to the wires the electric network available sets of ears, which are installed at the entrance of the electrical circuit and the lamp should ensure Connecting a wire with aluminum conductor cross-section of 2.5 or 4 mm from the input and equipment wires with copper conductor cross-section 0.5 -1 mm2 - from the lamp circuit.These terminals connect aluminum and copper wires to each other.Commercially produced eleven sizes of cl
amps, six of which are designed for 220 V and are intended for connection of wires from copper and aluminum conductor cross-section 0.5 - 2.5 mm.

Finally, a little general information.

Conventional notation: LB - white lights;LHB - lamp cold white color: LTB - lamp warm-white color.For lighting systems that require correct color rendering, lamp rings available, LTBTS, MDC respectively natural (F), warm white (TB) and day (D) color.The numbers after the letters indicate the lamp power in watts.For example, LB-20 stands for: white fluorescent lamp power of 20 watts.Combustion Duration

fluorescent lamps significantly longer than the incandescent combustion (1000 hours) and depending on the type of a few thousand hours.Luminous flux after 70% of the mean burning is reduced to 70% of the average of the nominal flow.Most lamps are used for a long time at room temperature and at rated voltage.Overvoltage and undervoltage reduce service life, but to an increase in voltage fluorescent lamps are much less sensitive than incandescent bulbs.(Remember, incandescent behave quite differently: when the voltage is sharply reduced lifespan, while reducing stress - increases dramatically).

fluorescent lamps are included in the network, together with control gear - gear.Lifetime inductors and capacitors PRA about 10 years.


Troubleshooting

Sometimes luminaire starts to "act up."What to do?

Features of operation of such lamps is the presence of the auxiliary circuit switching devices - a starter and throttle.If the scheme does not light a lamp, you need to check whether your power supply, as well as individual elements of the circuit switching on the lamp.

Normal operation Lamp essentially depends on external factors - from the supply voltage and ambient temperature.With proper power and all the elements of the scheme included the lamp may still does not light up, if the ambient temperature is less than + 10 ° C and if the supply voltage fluctuation exceeds 6-7%.Ignition of the lamp is usually not immediately, but after a few positives starter.The total duration of the ignition should not exceed 15 seconds.If during this time the lamp does not light, there may be a fault, which can be both in the tube and in the individual elements of the connection type.

lamp does not light.The reasons may be a fault:

a) power - for an open or poor contact;

b) starter - heating circuit does not close the lamp electrodes;

c) Throttle - open throttle in the winding;

g) cartridges - lack of contact;

d) of the lamp - the lamp electrode breakage.

Check and remedy these faults are made in the following order:

a) check the voltage across the contacts of the lamp holder and starter;

b) to replace the lamp.If the new lamp is lit, the lamp has been replaced faulty.

When the glow lamp phosphor, causing occurrence of auxiliary discharge, there is only one end of the lamp.The lamp flashes, but does not ignite.The reasons for this fault may be in the wiring circuit in the cartridge, in the lamp output, which glow phosphor absent.

Remedy is carried out in the following order:

a) lamp rearranged so that the defective and normal glowing ends of her reversed.If this interchange will be no glow, this lamp is defective and should be replaced by a new;

b) if there is no lamp replacement, glow, check the circuit on and lamp holder, remove the closures, if necessary, replace the cartridge.

glow at the ends of the lamp there and persists for a long time, but the lamp does not ignite.The reason must be sought in the fault starter cartridge or wiring.If the starter is removed and the glow disappears, then the starter must be replaced.If and when there is no starter on the ends of the lamp will glow, check the wiring and remove the starter cartridge available in their circuit.

included at the ends of the lamp appears dim and fading orange glow lamp does not light, and after a while the glow disappears.Such a lamp has to be replaced because it is air.


If the lamp is lit normally, but in the early hours of burning there is a strong darkening of its ends, and after a while it ceases to light up, the defective throttle, becausestarting and running currents have values ​​that do not meet the current-voltage characteristic.

To do this, check the value of start-up and operating currents.In some cases, the premature end of the lamp darkening may be caused by the poor quality of its cathodes.

If the lamp is lit normally, but the discharge is not uniformly fills the space between the electrodes, and in some areas in the form of a snake writhing, the defective throttle - the lamp current is too large.It is necessary to check the value of starting and operating the lamp current, and if they are within the limits specified in the current-voltage characteristic, the throttle must be replaced with a new one.If the current does not exceed the limits, in some cases, it may be a problem with the lamp itself - it is not well treated cathodes.The lamp several times to extinguish and light, turn it into chucks around its axis by 120 ° and once again ignite and extinguish.If after this discharge does not fill the entire space between the electrodes, the lamp must be replaced.

If the lamp periodically lights up and goes out, then the faulty lamp and starter.The lamp is defective becausethe voltage drop across the lamp during its combustion ignition voltage exceeds the discharge in the starter.It is necessary to check the voltage drop in the lamp.If it exceeds the values ​​specified in the table, this lamp should be replaced with a new one.If ignition voltage discharge in the starter below the minimum value, then the starter is defective.

lamp is lit normally, but is very dim, the light flux emitted by the lamp, is not sufficient.This is because the throttle does not provide proper operation of the lamp.If the operating current of the lamp is less than the minimum allowable value specified in the table, you should change the throttle.If the lamp current does not exceed the lower limit, it means that the lamp must be replaced because it contains very little mercury.

When you turn on the installation fuse spiral lamp, it must be replaced by a choke, asin his winding partially or completely broken insulation.

If any failure in installing fluorescent lighting installation must be immediately disabled.The cause of the fault must be clarified and resolved, since the fault of one element can cause damage to others.

Proper lighting APARTMENTS

Creating the right lighting provides optimal conditions for work and leisure, harmoniously combined in a single unit all elements of the interior - a very important task.
